Benchmark DAC1 USB D-to-A Converter Headphone Amp Black Rack Ear 24bit

Item Description
The DAC1 USB is a two-channel, 24-bit, 192-kHz Digital-to-Analog audio converter. It is, perhaps, one of the more significant recent advances in digital-audio conversion technology.
Listening to audio from the DAC1 USB is an absolutely truthful experience. The distortion free output is so pristine you can now hear detail which was previously masked by jitter induced artifacts and distortion. If the recording was exceptional, you’ll hear it; if it wasn’t, you’ll hear that as well.
The DAC1 USB is a 192-kHz converter, and will playback 192-kHz signals with a 52-kHz analog bandwidth. THD+N is an astonishing low -105 dB (0.00056%) measured at 0 dBFS, and -107 dB measured at -3 dBFS – at any playback frequency, at any sample rate, and with any degree of input jitter. The secret? UltraLock™ technology.
Additional features include: phase-coherence between units, auto-detection and processing of pre-emphasized digital audio, and an ultrahigh performance HPA-2 headphone amplifier with dual outputs. The DAC1 USB has an internal, international toroidal power supply.
The front panel level-control always adjusts the headphone output level. The front panel level-control can also be selected to adjust the output levels at the rear of the converter. Alternately, the output levels can be set at a fixed gain with precision, rear panel; 10-turn trim pots. The balanced output level range is +10 dBu to +29 dBu at 0 dBFS.
The DAC1 USB is essential equipment for mastering and recording studios, broadcast facilities, even audiophile home stereo installations, and all locations that require uncolored monitoring.
The DAC1 USB has all of the features of the DAC1 plus:

USB Audio 1.1 interface (96 kHz, 24 bits)

Programmable headphone gain - 2-settings (0 dB and -10 dB)

Programmable mute switch on left headphone jack
